EXPLOSlVE-ENGINE.

SPECIFICATION forming part of Letters Patent No. 738,860, datedSeptember 15, 1903.

Application filed January 8, 1902. Serial No. 88,849. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM W. TUoK, residing; at Richmond Hill, Queenscounty, ABBOT AUGUSTUS LOW, residing at Horseshoe, St. Lawrencecounty,and AUGUST IVASSMANN, residing at Halletts Point, Astoria, Queenscounty, State of New York, citizens of the United States, have inventedcertain new and usefullmprovements in EXp1osive-Engines,of whichthefollowingisa specificatiomsufficient to enable others skilled in theart to which the invention appertains to make and use the 7 same.

against a reciprocating piston and are de-j signed to obviate backpressure and noise by condensing, absorbing, and withdrawing theproducts of combustion through the medium,

of a stream of water flowing under pressure, substantially ashereinafter stated.

The invention consists, essentially, in combining with the exhaust forthe products of combustion a conduit through which water is passed underpressure in such manner that the products of combustion are caused toimpinge upon the flowing water by which they are withdrawn anddischarged, the continuously-flowing stream of water closing theexhaust-passage to the atmosphere, so that there can be no back pressureand resulting noise, vibration,or loss of power, as hereinafter moreclearly set forth.

In the accompanying drawings Figure 1 represents a front elevation ofour improvements as applied to a gas engine in which kerosene-oil isused, although it is to be understood that our improvements may be usedinv conjunction with any form of gas or explosive. Fig. 2 is a sectionaldetail of our ejector.

E is the engine of any design or manufacture, as before indicated, inwhich the power is generated by the explosion of a hydrocarbon gas orvapor or any other form of explosive producing products of combustion.

c is the ordinary exhaust pipe or passage.

P is a pump of any desired form or corn struction, operated preferablyby means of an eccentric 0 upon the power-shaft S of the engine,although this is not essential, since the pump or equivalent device maybe operated by any mechanical means, if desired, the essential featurein this connection being the provision of means whereby a continuousflow of water or other liquid may be maintained within the pipe orconduit A. In the drawings a pump P of ordinary and well-knownconstruction is indicated, supplemented by check-valves p p in the usualway, a regulating-valve V being added and interposed between thecheck-valve p and discharge-ejector I) for the purpose of regulating andadjusting the flow of water delivered by the pump. The ejector D may bemade in various ways mechanically and the form herein shown is presentedby way of illustration only, since the essential feature of constructionconsists in means for passing a stream of water across the opening e inthe lower end of the exhaust 6, through which the products of combustionare discharged from the engine E.

It is obviously preferable to have the lower end of the conduit for thedischarge of the products of combustion run parallel to the adjoiningportion of the water-conduit, so that the flow of gas and liquid will bein the same direction as indicated, although the products of combustionmay be caused to impinge against a stream of water at any desired anglewithout departing materially from the spirit and intent of ourinvention. In the drawings we show the ejector D as interposed betweenthe lower end of the conduit c and the upper end of the water-pipe A,said ejector having the two passages d and c merging into each other andinto the common discharge or outlet D, by which the combined water andproducts of combustion are conducted to the desired point for ejectment.The tendency of the constantlyflowing stream of water in the passages A,(Z, and D is to create suction through the discharge-passage 6, so thatthe products of combustion as they are forced through the discharge-pipec readily enter into and are absorbed by the stream of water, and thiswithout direct impact against the atmosphere. The stream of water alsoforms a continuous seal to the end of the discharge-pipe (2, so thatthere can be no communication with the atmosphere under any conditions,and consequently no back action and no noise or vibration.

By our method the removalof the products of combustion is complete andeffective, no bad or impure air being left within the cylinder orexhaust-pipe to contaminate and impair the efficiency of succeedingcharges, rendering the operation of the engine more economical andeffective, as has been proved by experiment and use, while, as beforestated, avoiding back action, vibration, and noise, the stream of watersealing the dischargepipe, lubricating the same, and tending constantlyto suck out and absorb the products of combustion.

What we claim as our invention, and desire to secure by Letters Patent,is

1. The combination with an explosive-engine, of an exhaust-pipe leadingtherefrom, an ejector connected with the lower end of said exhaust-pipe,said ejector having a diaphragm extending beneath such connection withthe exhaust-pipe, means for forcing a stream of water from beneath saiddiaphragm across the discharge-opening of the exhaust from said ejectorabove the diaphragm, and a common discharge for the exhaust and waterfrom said ejector, substantially as shown and described.

2. In an explosive-engine the combination with the exhaust-pipe and awater-pipe, of an ejector interposed between the two and having passagesseparated by a partition, one of said passages being connected with theexhaust-pipe, and the other with the dischargepipe from said pump, and adischarge-pipe connected with the discharge end of the ejector in linewith said partition whereby said partition constitutes a water sealextending across the discharge end of the passage connected with theexhaust, substantially asv and for the purpose specified.

The combination with an explosive-engine and its exhaust-pipe, of awater-pump connected directly with the power-shaft of said engine, apipe leading from said pump, a regulating-valve in said pipe, an ejectorconnected with said pipe and with the exhaust-pipe and having a portionextending at substantially right angles to said pipes and provided witha longitudinal partition extending from the point of junction of itscurved branches, and a common discharge-pipe for said water and exhaustconnected with the discharge end of the ejector with said partitionextending substantially in axial line therewith, whereby thewaterfiowing through the lower branch of the ejector creates a suctionthrough its upper branch and the water forms a continuous seal to theend of the discharge-pipe and to the exhaust, all substantially as shownand described.

4. The combination in an explosive-engine and with the exhaust-pipeleading therefrom, of an ejector having upper and lower branches forconnection with said exhaustpipe and with a pipe leading from a pump anda lateral branch at right angles thereto for connection with adischarge-pipe common to both of said branches, -said ejector beingfurther formed with a longitudinal partition integral with and joiningthe said upper and lower branches at their junction and extending to apoint approximately at the outer end of its lateral branch to constitutewith the water beneath the same a continuous seal to the end of thedischarge-pipe from the exhaust of the engine to avoid back action andvibration, all substantially as shown and described. I

5. As an improved article of manufacture, an ejector attachment forexplosive-engines comprising in a single integral element an ejector-bodyhavin g upper and lower branches oppositely curved from thebody portion which latter is contracted at its outlet end, and alongitudinal partition joining the adj acent curved portions of theupper and lower branches and extending lengthwise of the body portion tothe point where the same is contracted and the whole adapted to servesubstantially as and for the purpose specified.
